Nepomorpha genera

Ranatra is a genus of slender predatory insects of the family Nepidae, known as Water mantis, water scorpions or water stick-insects. There are more than 140 Ranatra species found in freshwater habitats around the world, both in warm and temperate regions, with the highest diversity in South America (almost 50 species) and Asia (about 30 species, reviewed in 1972). Fewer are found elsewhere, but include several African, some in North America, three from Australia and three from the Palearctic, notably the relatively well-known European R. linearis. Since Ranatra belongs to the family Nepidae w

Lethocerus is a genus of the hemipteran family Belostomatidae, known colloquially as giant water bugs, toe biters and electric light bugs, distributed in tropical, subtropical and temperate areas of the world. The greatest diversity of species occurs in the Americas, with only a single species in Europe, two in Africa, two in Australia and three in Asia. It includes the largest true bugs with species capable of reaching a length of over . The South American L. grandis and L. maximus are the only species to commonly exceed , with more typical lengths for the remaining species being between . Le

Belostoma is a genus of insects in the hemipteran family Belostomatidae, known colloquially as giant water bugs. Members of this genus are native to freshwater habitats in the Americas, with the greatest species richness in tropical South America. Most species in the family Belostomatidae have historically been included in Belostoma, but several of these have been moved to other genera (although Belostoma remains a genus with many members). 9 species are claimed to be found in Northern America, but the genus Belostoma is actually divided into 16 subgroups containing about 70 species.

Abedus is a genus of giant water bugs (family Belostomatidae) found in freshwater habitats in southern United States, Mexico and Central America. Sometimes called ferocious water bugs, these brown insects typically are between long, although A. immaculatus only is about , making it the smallest North American belostomatid and possibly worthy of separation in its own genus. Otherwise the different Abedus species are very similar and can often only be separated with a microscope. They will bite in self-defense, which is painful but not dangerous.

Corixa is a genus of aquatic bugs in the family Corixidae. The fossil species C. elegans is from the Rott Formation in Nordrhein-Westfalen (Oligocene of Germany).

Ambrysus is a genus of creeping water bugs in the family Naucoridae. There are more than 90 described species in Ambrysus.

Buenoa is a genus of backswimmer. It was created by George Willis Kirkaldy in 1904 to include all species of Anisops from the Western Hemisphere with a two-segmented front tarsus in males, reserving the latter genus for Eastern Hemisphere species with a one-segmented front tarsus in males. It contains 69 described species.

Micronecta is a genus of aquatic bugs in the family Micronectidae (formerly in Corixidae) erected by George Willis Kirkaldy in 1897. Species have been recorded mostly from Europe, Africa, Asia and Australia and are sometimes placed in up to 10 subgenera (with species incertae sedis); the subgenera Dichaetonecta and Micronecta are recorded from Europe.
